مولانا حمید الدین
گزشتہ مہینہ مولانا حمیدالدین صاحب محدث اور ان کے ایک کمسن نواسے مولانا اسعد مدنی کے صاحبزادے نے کار کے حادثہ میں وفات پائی، مرحوم مولانا حسین احمد صاحب مدنی کے قریبی عزیز تھے، ان کی پوری زندگی دینی علوم خصوصاً حدیث نبوی کی خدمت میں گزری، ابتداء میں دارالعلوم دیوبند میں مدرس تھے، کچھ دنوں تک دارالعلوم ندوۃ العلماء میں بھی حدیث کا درس دیا، ادھر عرصہ سے مدرسہ عالیہ کلکتہ میں شیخ الحدیث تھے، علم کے ساتھ عمل اور اصلاح و تقویٰ کے زیور سے بھی آراستہ اور طبعاً خاموش، متین اور مرنجان مرنج انسان تھے، یہ المناک حادثہ بجائے خود ایک طرح کی شہارت ہے۔ اﷲ تعالیٰ، حدیث نبوی کے اس خادم کو اپنی رحمت و مغفرت سے سرفراز فرمائے، دارالمصنفین اس حادثہ میں مولانا اسعد مدنی کا شریک غم ہے۔ (شاہ معین الدین ندوی، دسمبر ۱۹۶۸ء)
This research is a quantitative approach with the aim at knowing: (1). The relationship between self-efficacy and the role of the teacher by learning based on self-regulation. (2). The contribution given by self-efficacy and the role of teachers in self-regulation based learning. (3). Levels of self-efficacy and the role of teachers in learning based on self-regulation. The subject of this study was acceleration in one of the Public High Schools in Surakarta as many as 115 people. This study is a principled study on population studies. Based on the results and analysis using multiple regression it is known that the correlation coefficient R = 0.375 (p = 0.000: p <0.05), which means that there is a significant relationship between self-efficacy and the role of teachers with self-regulation. The total contribution given by the two independent variables in this study amounted to 14.1%, and for both categorizations the independent variables namely self-efficacy and the role of the teacher were at a high level, and the dependent variable of learning based on self-regulation was at a very high level. Key word: Self-Regulated Learning, Self-Efficacy, The Role of Teachers
Wheat straw is a non-wood agricultural residue which serves as an excellent fibrous source for pulp and paper industry. In the present work, TCF bleaching sequences were developed for indigenous variety of AS/AQ wheat straw pulp. Different chemicals such as acid, oxygen, oxone, dithionite, alkali and hydrogen peroxide were optimized in different stages and sequences at varying doses of bleaching agents and reaction conditions. Multistage TCF bleach sequences i.e., AOOxPP*, AOOxEP, AOOxYP, AO′Ox′P′ are resulted from various optimization trials during the study. It was very promising to find out that cellulose remained protected whereas most of the residual lignin was removed during the process. Most of the hemicelluloses were washed away during bleaching. However, it is quite evident from the pulps’ sugar analysis that only a small fraction of hemicelluloses remained intact in the bleached pulp which is important in fiber preparation and its bonding during papermaking process. Similarly, hexenuronic acid was also removed during successive stages of bleaching that may be the causes of reduction in fiber strength, brightness and brightness stability. The results also revealed that the developed bleaching sequences are effective and selective to fully bleach the pulp with brightness gain greater than 80% ISO without deteriorating its fibre characteristics such as kappa number, viscosity, strength and brightness stability etc. A considerable reduction in effluent load with reduced toxicity and zero AOX level shows the advantage of process over chlorinated bleaching processes. Thus the study provides enough evidence to fill the gap between producing quality products and requirements for a healthy environment using TCF bleaching sequences.
